How to Recognize the Chrysler REL Alpine
Compare the design, controls, display and features listed below with your factory-installed radio - the Chrysler REL Alpine is easy to tell apart once you know what to look for.
Identifying details:
- 6.5" touchscreen in the centre of the dash
- Built-in navigation with factory map data
- Sales code REL on the chassis label
- Serial number starting with TQ1AA, TT1AA, TH1AA, THAAA, TCAAA
It is the Chrysler REL Alpine when:
- the chassis label carries the REL sales code
- the label serial begins with TQ1AA, TT1AA, TH1AA, THAAA, TCAAA
- the vehicle was built between 2008-2013
- the 6.5" touchscreen is the one the Alpine family uses
REL spans a wide part-number range (P05064053, P05064925, P05064927, P05064944/945, P05064954/955, P05107096, P68252828). If your speakers are badged Alpine and the radio looks like a MyGIG with 6.5-inch touchscreen and HDD nav, REL is most likely. Harman RER carries a separate part-number set.
About the Chrysler REL Alpine
The Chrysler REL Alpine is an original factory-installed infotainment system developed for selected Chrysler vehicles. Designed to provide reliable audio playback and vehicle integration, this unit may also offer Bluetooth connectivity, touchscreen controls, CD/DVD playback, navigation or multimedia support, depending on the specific version.
REL Alpine is the high-volume Alpine-audio MyGIG NTG4 variant - 6.5-inch touchscreen with HDD navigation, paired with the Alpine speaker/amp package fitted across Chrysler/Dodge/Jeep/Ram mid-to-high trims through 2013. Boot logo shows the brand badge then the MyGIG splash.
Between 2008-2013 the Chrysler REL Alpine appeared across a number of Chrysler models, usually on vehicles using the Alpine multimedia platform. It stayed in production long enough to become a common sight in that generation of cars.
Typical features include:
6.5" touchscreen
AM/FM radio
Built-in navigation with factory maps
Hard-drive music storage for copied discs
CD playback
AUX and USB input*
Steering wheel control support
Anti-theft security code
*Availability varies with the vehicle configuration.
Like many factory-installed radios, the Chrysler REL Alpine is secured with an anti-theft system. If power is interrupted after replacing or disconnecting the vehicle battery, the unit may demand the original radio code before it can be used again.
Background on the platform itself is published by Alps Alpine, the unit's manufacturer.
Where to Find Your Chrysler REL Alpine Serial Number
Your unlock code is bound to the radio's serial number, so it is the one detail the form asks for. The number lives on the label stuck to the chassis of the radio itself.
On this unit: Top of the chassis on a white sticker, slightly right of centre. Three 7mm bolts and two clips release the dash bezel; the radio slides forward by about four inches and the label is visible from above. Harness disconnect is not required to read the label.
How to reach the number:
- Pull the unit forward with release keys (a few dollars online) - the wiring can stay connected.
- Find the white label on the housing and read the serial off it - it sits beside the barcode.
- Type it into the form exactly as printed, without spaces.

What Usually Triggers the Code Screen
A locked Chrysler REL Alpine is almost always the result of one of four everyday situations, none of which mean anything is broken.
A battery swap
A replacement battery - or a flat one after the car sat for a while - cuts power to the radio, and the anti-theft system arms itself the moment power returns.
A repair cut the power
Alternator, starter or fuse-box work usually means disconnecting the battery - and the radio locks itself as a side effect of the repair.
You bought the car used
No handbook, no code card, seller long gone - none of it matters. The radio's own serial number carries everything needed to calculate the code.
A replacement radio
A used unit from a donor car always arrives locked, and the code from your old radio will not fit - the code follows each radio's own serial number, so order it for the serial on the REPLACEMENT unit.
Whichever of these applies, the fix is identical: the serial number off the radio, the form at the top of this page, and the code is emailed in seconds.

The part number is printed on the label on top of or on the side of the radio chassis, usually next to the serial number. If yours appears above, the Chrysler REL Alpine is the right page.
Where Was the Chrysler REL Alpine Installed?

| Chrysler 200, 300, Town & Country (Alpine premium trims) | 2008-2013 | |
| Dodge Avenger, Charger R/T, Challenger R/T, Durango, Journey (Alpine premium) | 2008-2013 | |

The vehicles listed above are the most common factory applications for the Chrysler REL Alpine. Equipment packages and regional specifications differ, so verify the radio using its design, serial number or part number before requesting a code.
Once the code arrives
The code goes straight into the radio, not into the car's menus.
- Give the radio power - key to accessory is enough - and wait for the code prompt.
- The screen shows a numeric keypad for the four digits.
- Punch in all four digits, first to last.
- Verification happens by itself once the fourth digit is in.
- The security screen disappears and the unit returns to normal operation.
Troubleshooting the Chrysler REL Alpine
The screen shows a wait timer
The timer is the radio guarding itself after failed entries - power on, patience, then try again. Three wrong entries triggers a 60-minute "WAIT" countdown on screen. Keep the ignition in RUN or ACC for the timer to count down - cutting power resets it to 60 minutes. Once the timer expires the keypad reactivates and the correct code clears the screen.
The label is not where I expected
Only the radio itself carries it - bring the unit out and the label is right there. Top of the chassis on a white sticker, slightly right of centre. Three 7mm bolts and two clips release the dash bezel; the radio slides forward by about four inches and the label is visible from above. Harness disconnect is not required to read the label.
Locked again after it was fine
Nothing is broken. Any interruption to the 12V supply brings the lock screen back. Loss of constant 12V - dead battery, battery replacement, alternator service, body-shop repairs that disconnect the battery, or removal of the radio from the dash. The most common report on REL is from Ram trucks after a winter dead-battery jump.
This radio looks like several others
A few models in this family share the same face, so the label is what settles it. REL spans a wide part-number range (P05064053, P05064925, P05064927, P05064944/945, P05064954/955, P05107096, P68252828). If your speakers are badged Alpine and the radio looks like a MyGIG with 6.5-inch touchscreen and HDD nav, REL is most likely. Harman RER carries a separate part-number set.
Save the code: it stays valid, so the next battery change costs you nothing.
